Are the ground states of randomly interacting bosons random?

TL;DR

This paper investigates many-boson systems with random interactions and finds that their ground states are structured, dominated by collective cluster condensates rather than being random.

Contribution

It provides a systematic analysis showing that ground states of randomly interacting bosons are organized around collective configurations, challenging the assumption of randomness.

Findings

Ground states are dominated by collective cluster condensates

Ground states are not random but structured

Systematic study of random bosonic interactions

Abstract

Bosonic degrees of freedom and their emergence as a part of complex quantum many-body dynamics, symmetries, collective behavior, clustering and phase transitions play an important role in modern studies of quantum systems. In this work we present a systematic study of many-boson systems governed by random interactions. Our findings show that ground states of randomly interacting bosons are not random, being dominated by a few collective configurations containing condensates of clusters.
